Grain – Fine silver crystals in the light-sensitive emulsion of film that react when exposed to light and turn black. The slower the film speed the finer the grain and the faster the film speed the more present the grain. Larger film formats can be enlarged without much grain is noticed whereas 35mm formats may see noticeable grain beyond an 8 x 10 inch print.

Gray Card- A neutral card that is helpful for measuring light and leads to consistent exposures.
